IMPROVEMENT IN TUBE-WELLS.

Specification forming part of Letters Patent No. 176,528, dated April25, 1876; application filed April 4, 1876.

To all whom it may concern Be it known that I, STEPHEN HENRY, of Marshfield, Plymouth county, Massachusetts, have invented a new and. ImprovedTube- Well, of which the following is a specification: v

My improved tube-well consists of a detachable point for driving, with ashoulder, against which the tube acts, and a shank extending up in thetube, and fitting nicely for a short distance, and then tapering to apoint, the object being to secure unobstructed entrance to the tube forthe water by raising the tube up to the conical part of the shank afterdrivin g the plug to the depth required, and in case water is not foundwhen the tube is raised it can be let down on the point again and drivenfarther. In the common tube-wells in'uch difficulty occurs by thefilling of the perforations provided above the point for admitting thewater, which this contrivance is calculated to avoid.

Figure 1 is a section of my improved tubewell, the parts being connectedtogether as for driving; and Fig. 2 is a section of the tube and sideelevation of the point, the parts being dt taehed as adjusted, afterdriving, to admit the water to the tube.

Similar letters of reference indicate corresponding parts.

A is the point; B, the shoulder on which the tube rests; O, the shankextending up into the tube; D, the tapered point, and E the tube.

It will be seen that in case water is not found in suflicient quantityafter the tube has been raised it can readily be let down again on thepoint D for driving it still farther.

Having thus described my invention, Iclairn as new and desire to secureby Letters Patent The point A, having shoulder B, shank G, and point D,combined with tube E, substantially as specified.

STEPHEN HENRY.
